ActionScript 2.0 :: XML SendAndLoad Location Header?

I have a RESTful resource that gets looked up from a flash widget client. If the resource is not found, the ActionScript will create the resource by posting to a URL like /articles.xml with the appropriate data. If this is successful, the backend returns a 201 status and sets the HTTP Location header with the address of the newly-created resource. My understanding was that ActionScript, upon seeing the location header set, would essentially grab the document at that URL like a redirect and make it available to me in the XML object. Here's some code:

Code:
var create_params:String = "<article><foo>abc</foo><bar>xyz</bar></article>";
var create_xml:XML = new XML(create_params);
var reply_xml:XML = new XML();
reply_xml.ignoreWhite = true;
create_xml.ignoreWhite = true;
[Code] .....

The resource gets created as expected, which means the 'send' part works fine. And if I examine the results returned in a sniffer, or test using Curl, the Location header is indeed set by the server side. However, the Flash never makes a request to my server for the new resource and therefore when I examine the XML object, there isn't any data there. Is this not how sendAndLoad is supposed to react to the location header? I can't seem to find any documentation on it or other people with similar issues, so I'm kind of puzzled. If it doesn't auto-redirect to grab the new resource, is there a way I can pull the value of the location header into a variable so I can at least manually fetch it?
